Heng long new 5.3 dual sound MFU

[Sub]

Hi.
I think you are probably right with your assumptions.
Some retailers are offering these as upgrades and it was just a thought i had ( must be carefull ).
i think i will live with what i have for the shorterm as i have some open panzer boards to fit after i have done making all the upgrade parts i wish to do, just finished making some drive axle ball bearing supports up on the lathe and converting the turret ring to full 360.
Probably fit bearings to the wheels and look at manufacturing some front idler track tensionsers then on to making some sound boards etc etc.
Onwards and upwards.
Regards.
